ENVIRONMENATLLY CONTROLLED POULTRY

HOUSESINSIDE TEPERATURE CONDITIONS VARY WITH OUTER ENVIRONMENTAL TEMPERATURE CONDITIONS

ALL PARAMETERS SHOULD BE GIVEN BY MECHANICAL MEANS.

VENTILATION SHOULD BE GIVEN BY ARTIFICIAL

THE DIRT AIR SHOULD BE REMOVED BY ARTIFICIAL METHOD BECAUSE ALL SIDES OF HOUSE IS COVERED.

FRESH AIR SHOULD BE BROUGHT INTO THE HOUSE BY MECHANICAL METHODS.

FOR THESE FANS ARE USED TO DRAW AIR INSIDE THE HOUSE.

TYPES OF ARTIFICIAL VENTILATION

DUCT VENTILATIONAIR IS BROUGHT INTO THE HOUSE THROUGH DUCTS PROVIDED ON THE EITHER SIDES OF THE HOUSE.

EXHAUST FANS ARE PROVIDED ON THE SIDE WALLS OF THE HOUSE AT REGULAR INTERVALS.

TUNNEL VENTILATIONMOST EFFECTIVE IN TROPICAL CLIMATE

DUE TO HIGHER AIR EXCHANGE RATE & FASTER AIR MOVEMENT…2-3.5 MTRS/SEC.

FRESH AIR ENTERS THE HOUSE AT ONE END AND PULLED THROUGH THE HOUSE IN LONGITUDINAL DIRECTION BY MEANS OF HIGH PERFORMANCE FANS

TUNNEL VENTILATION

CROSS VENTILATIONIN THIS SYSTEM COOLING PAD IS

INSTALLED IN ONE END OF THE HOUSE.

EXHAUST FANS ARE INSTALLED IN THE OPPOSITE SIDE WALL OF THE HOUSE.

THESE FANS WILL SUCK THE AIR FROM COOLING PAD ALONG CROSS OF THE HOUSE.

THESE FANS MAY CREATE DEAD SPOTS WHILE RUNNING.

WORKS BEST IN 10M WIDE HOUSE

CROSS VENTILATION

COOLING PAD

EXHAUST FANS

SIDE WALL VENTILATION

FANS AND INLETS ON THE SAME SIDE WALL
